Electrical batteries and super-alloys


When it is not primary, cobalt is a by-product of copper and nickel. It can also be extracted from numerous other ores such as smaltite and cobaltite...

When used in powder form as a binder for hard metals, it is an essential element in the manufacture of super-alloys for the aeronautical sector and for the manufacture of gas turbines, cutting tools, ceramics and catalysts.

Cobalt is malleable, ductile and ferromagnetic at high temperatures, making it a key element in the production of electrical batteries, notably for the new technologies and electric vehicles market, which is enjoying significant growth.
